Lex (*.l)
.It
Yacc (*.y)
.El
.Pp
.Sh TARGETS
.Bl -tag -width "deinstall-prog "
.It Ar ${PROG}
Compile/link the ${PROG} executable from the specified source files.
.It Ar ${GMONOUT}
Compile/link a profiled version of ${PROG}.
.It Ar clean-prog
Clean up object and executable files.
.It Ar cleandir-prog
Clean up for packaging.
.It Ar install-prog
Install program to the target installation directory
(see
.Xr csoft.common.mk 5 ) .
.It Ar deinstall-prog
Uninstall program from the installation directory.
.El
.Sh VARIABLES
.Bl -tag -width "CONF_OVERWRITE "
.It Ev PROG
Filename of target executable.
Platform-specific transforms may be applied to the name.
.It Ev PROG_TYPE
Type of application (used on some platforms by
.Xr build.proj.mk 5 ) .
Set to
.Sq CLI
for a command-line utility,
.Sq GUI
for a graphical interface and
.Sq DAEMON
for a server program.
Defaults to
.Sq CLI .
.It Ev BINDIR
Target installation directory for executables
(usually set by configure).
.It Ev PROG_INSTALL
If set to
.Sq Yes ,
the
.Ar install
target will install the program, otherwise it will be a no-op.
Defaults to
.Sq Yes .
.It Ev PROG_GUID
A Global Unique Identifier (GUID) for the program.
Exact interpretation is platform-specific.
.It Ev GMONOUT
Output filename for profiled version of the program.
.It Ev CC
Compiler for C, C++ and Objective C sources.
Defaults to
.Sq cc .
.It Ev CFLAGS
Compiler flags for C sources.
Defaults to
.Sq -O2 -g .
.It Ev CXXFLAGS
Compiler flags for C++ sources.
Defaults to
.Sq .
.It Ev OBJCFLAGS
Compiler flags for Objective C sources.
Defaults to
.Sq ${CFLAGS} .
.It Ev CPPFLAGS

.It Ev WINRES
(Specific to the win32 platform)
Resource file to use with
.Xr windres 1 .
.It Ev SHARE
List of data files to install into
.Dv ${SHAREDIR} .
Files must have been generated from the build process.
.It Ev SHARESRC
Similar to
.Ev SHARE
for non-generated files to be copied from the source directory.
